PREFACEOur latest offering ‘MHT-CET : 20 Question Paper Set’ is a meticulously designed book to assessthe threshold of knowledge imbibed by students over a period of two years in junior college.The book charts out a compilation of Practice Question Papers aimed at students appearing for theontentMHT-CET examination. Every question paper in this book has been created in line with theexamination pattern and touches upon all the conceptual nodes of Physics, Chemistry, Mathematicsand Biology. The questions throughout this book are specifically curated by our expert authors withan astute attention to detail. The core objective of this book is to gauge the student’s preparedness toappear for a competitive level examination.They say, ‘with the right tools, even ordinary men achieve extraordinary results’. We aspire thisbook to be the perfect tool that’d help students to take off their career in the most extraordinary waypossible.The journey to create a complete book is strewn with triumphs, failures and near misses. If you thinkCwe’ve nearly missed something or want to applaud us for our triumphs, we’d love to hear from you.Please write to us on : mail@targetpublications.orgpleA book affects eternity; one can never tell where its influence stops.mBest of luck to all the aspirants!Yours faithfully,PublisherSaEdition: ThirdDisclaimerThis reference book is transformative work based on textual contents published by the Maharashtra State Board of Secondary and Higher Secondary Education, Pune.
